Late last week, a video leaked that appeared to show a dream sequence - reportedly Serena's, but possibly Blair's - from the 100th episode. We've been asked not to post it on copyright grounds, but we can still start a discussion.

As we know, the royal wedding takes place January 30, with two episodes (January 16, January 23) leading up to the watershed event. But for all intents and purposes, January 30 is the date fans are focused on.

In the video, Serena was singing "Diamonds Are a Girl's Best Friend," a la Marilyn Monroe, with Nate, Chuck and Louis as her backup dancers. The setting for this unexpected musical number: Blair's foyer.

The chorus line alone would be noteworthy, but that's not even all. Queen B shows up shortly after.

At the end, Blair herself makes an appearance, a la Audrey Hepburn in "Breakfast at Tiffany's." As Dan walks over to her, she grabs his hand and Serena grabs the hand, starting a tug of war over Humphrey.

The video, reportedly taped by Chace Crawford, has understandably sparked much debate in recent days. Did you see it? What did you think of it? What does it represent, and what will happen next month?
